8、Works and debugging methods1、 本止回阀主要由阀体、阀盖、阀板组件、平衡锤、活塞组件与针型调节阀等组成.启动水泵时,依靠阀门进口介质的压力作用,压力水通过疏水导管进入活塞腔内,使活塞伸出并与流通介质共同推动阀板开启,同时使活塞伸出部分预置到位,平衡锤越过最高点,这样保证阀板的最大开度,使之不上下摆动.当水流停止时水泵停机由于阀板的自重使阀板自由下落关闭,但由于活塞处于伸出位置顶着阀板,使阀板不能全部关闭,还剩下约1/5左右的开启间隙,这样介质可以通过,减弱了水锤峰值压力,限制了破坏性水锤的发生.阀板压在活塞端部,活塞腔内的水阻碍了活塞的快速回伸,阻止阀板的关闭,这时
9、阀板在介质的背向压力作用下,推动活塞向后滑移,在活塞的推动下,活塞里介质通过调节阀又回到了系统中,活塞也缓慢回到原来位置,阀板最终完全关闭.1.the check valve consists of valve body, valve cover, valve plate assembly, the counterweight, the piston assembly and the needle valve and other components.When start the pump, relying on imports of medium pressure valves, press

11、ot to swing up and down.When the water stops since the valve plate of the weight of the valve plate free-fall off, but since the piston in the extended position against the valve plate, the valve plate is not fully closed, leaving about 1/5 or so of open space This medium can be, and has reduced wat
12、er hammer peak pressure, limiting the destructive water hammer occurs.The valve plate against the piston end, piston cavity water hinders rapid piston back stretch, stop valve plate closed, then the valve plate at medium back pressure, push the piston back slip, the piston driven by the piston in th
13、e media through the valve back to the system, the piston is also slowly return to its original position, the valve plate eventually completely closed.2、 阀板缓闭开度的调整slow closing valve plate to adjust the degree of opening活塞伸出的长短,调节阀开度的大小,控制着活塞腔内的容量和阀板关闭的延缓时间.缓闭开度大,泄水时间长,水锤小；反之开度小,泄水时间短,水锤的形成就可能大,因此在结构上
14、缓闭开度调节器,用拉杆来控制活塞的伸出长度.开始调试时,可将活塞伸出总长拉杆退出长度即活塞总长的三分之二,然后停泵,检查水锤的大小和阀板能否关闭,水锤大,说明开度小；如果阀板关闭太慢,说明活塞伸出太长.经调试到理想开度后,即可用调节螺母固定拉杆,确定活塞伸出的长度.应该注意的是：活塞伸出的长短的调整与供水压力,输水距离,相对高差等工况有很大关系,它们之间是成正比例关系.另外,缓闭时间的长短,还可用针型调节阀的开度大小来控制,这个时间可控制在060秒,或者更长些.Extending the length of the piston to adjust the size of the valve

After commissioning the ideal degree of opening , the lever can be fixed by adjusting the nut , determine the length of the piston out . It should be noted that: the length of the piston out of adjustment and water pressure
18、 , water distance , relative elevation and other conditions have a great relationship , it is proportional to the relationship between them. In addition, the slow closing length of time, but also with a needle valve to control the size of the opening degree , this time can be controlled from 0 to 60
